WHIFFLETREE-CLIP.

SPECIFICATION forming part of Letters Patent No. 307,914, dated November 11, 1884.

Application filed April 5, 1884. (N model.)

To all whom it may concern.-

Be it known that I, ROBERT S. CLARK, a citizen of the United States, residing at Hele- 11a, in the county of Lewis and Clarke and Territory of Montana, have invented certain new and useful Improvements in \VhiffletreeOlips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of whiffietree-clips which'are used on double or single trees for connecting the single-tree to the double-tree or to the trace; and the object of my invention is to render such clips readily detachable and adjustable, so that they may be -removed or replaced with facility and also readily adjusted on the tree. The clip may be applied to double-trees, the ends or middle of single-trees, and mother objects to which it may be found applicable-as, for instance, neck-yokes, poles or shafts of vehicles, or plow-beams-and may be removed with facility in case the part to which it is attached should be broken.

In the accompanying drawings, Figure 1 is a side view 5 Fig. 2, a plan View; Fig. 3, a plan View of the under side of the device. Figs. 4. and 5 represent the parts detached from each other.

The clip consists of two pieces of plate, sheet, or cast metal, A and B, each of which is so formed, cast, or bent that, when they are hinged or pivoted together, they may be made to encircle the ends of the single-tree or part to which they are attached. The end of the upper part, A, projects forward from the part which clasps the tree in such a manner as to form an extended plate, I), and ring 0, and the end of the lower part, B, is extended forward in a similar manner to form the plate I) and ring 0. The pieces A and B are connected together by forming their edges in such amanner that they interlock with each other. In other words, projections formed on the one project within slots cut in the other. By this construction the parts may be locked together, and when so locked may be secured firmly in position by means of the bolt or pin which passes through them.

Each of the parts is provided with holes I in the sides of which are cut nicks or notches, and the under sides of the hole passing through the lower part are raised in such a manner as to form inclined curves or spiral surfaces S. The connecting or looking bolt H has projecting lugs h, which travel upon the said spiral surfacesor shoul ders h, and upon the under sides of the spiral surfaces are cut nicks or notches 0, so made and arranged that when the bolt is turned or forced home the lugs h catch within the nicks or notches 0, and thus the bolt is secured in position.-

In order that the parts may be adjusted upon the tree or detached therefrom with facility, the clip is provided with a hinge-joint of novel construction. The upper part, A, is bent or cast in such a manner as to form a right angle, and a hole, 1?, is cut in the part thus bent or extended. The lower part, B, is bent in a similar manner, and a hole, 1?, is cut therein. NotchesV are cut in the part A for the reception of projections formed upon the part B, and similar notches V areformed on the part B for the reception of projections formed upon the part A. At the point where the strap A is bent at a right angle a slit, X, is cut therein, extending half-way across the strap, and a similar slit is cut in the strap B. The parts are connected together in such a way as to form a hinge-joint by slipping the slits, respectively, over the parts of the straps adjacent-thereto, as is shown in the drawings.

Having thus described my invention I claim, and desire to secure by Letters Patent of the United States 1. The combination of the part or strap A, provided with a slit X, and the part or strap B, provided with a slit, X, as and for the purpose described.

2. The strap A, having a slit, X, the strap B, having a slit, X, and the means for clamping the parts together, all combined as and for the purposes described.

In testimony whereof I aflix my signature in presence of two witnesses.

ROBERT S. CLARK.
